CodeIgniter
Validation is an important process while building web application. It ensures that the
data that we are getting is proper and valid to store or process. CodeIgniter has made
this task very easy. Let us understand this process with a simple example.
Example
Create a view file myform.php and save the below code it in
application/views/myform.php. This page will display form where user can submit
his name and we will validate this page to ensure that it should not be empty while
submitting.
My Form
Name
Create a view file formsuccess.php and save it in
application/views/formsuccess.php. This page will be displayed if the form is
validated successfully.
